Abstract (en)

[origin: WO2021111156A1] The present disclosure relates to a method for improving the reading and/or writing phase in storage devices including a plurality of non-volatile memory portions managed by a memory controller, comprising: providing at least a faster memory portion having a lower latency and higher throughput with respect to said non-volatile memory portions and being by- directionally connected to said controller; using said faster memory portion as a read and/or write cache memory for copying the content of memory regions including more frequently read or written logical blocks of said plurality of non-volatile memory portions. A specific read cache architecture for a managed storage device is also disclosed to implement the above method.
